WebJul 6, 2012 · The IRF7 promoter contains androgen responsive elements and higher levels of IRF7 have been seen in the lungs of female Norway rats compared to males . We postulate that the lower R-848 stimulated pDC IFN-α production in male infants is at least partly due to androgen effects on IRF7 levels within the first six months of life. WebNov 17, 2024 · Plasmacytoid dendritic cells (pDCs) are the key producers of type I interferons (IFNs), thus playing a central role in initiating antiviral immune response. Besides robust type I IFN production, pDCs also act as antigen presenting cells post immunogenic stimulation. Transcription factor Irf8 is indispensable for the development of both pDC …
WebNov 17, 2024 · Plasmacytoid dendritic cells (pDC) sense viral RNA through toll-like receptor 7 (TLR7), form self-adhesive pDC–pDC clusters, and produce type I interferons. This cell adhesion enhances type I... WebResults: IRF7 activation was induced in pancreatic pDCs in experimental AIP. siRNA-mediated knockdown of IRF7 expression prevented AIP development, which was …
WebSep 13, 2012 · Phosphorylation levels of proteins involved in the TLR7 pathway including IRF7 were measured in pDCs by phospho-flow cytometry at baseline and at different time …
WebJul 25, 2024 · Considering that IRF7 is constitutively expressed in pDC and monocytes, whereas in most other cell types IRF7 is induced by innate IFN priming, this result suggests that IRF3 might be able to...
WebAug 13, 2024 · The IRF7 deficient pDC was severely impaired for type I or type III IFN production in response to influenza A virus infection 25. Moreover, an increased viral replication and reduced type I IFN production was observed for IRF7-deficient fibroblast or pulmonary epithelial cells in culture. In marked contrast to earlier observations, our data ... greene tax service sumter scWebJun 19, 2024 · To elucidate pDC immunomodulatory functions, we developed a mouse model in which IRF7 signaling is restricted to pDC. Despite undetectable levels of IFN-I protein, pDC-restricted IRF7 signaling controlled both viruses and was sufficient to protect mice from lethal CHIKV infection. fluid filled bump on lipWebFollowing phosphorylation, IRF7 translocates to the nucleus and initiates the transcription of type I and type III IFNs.
